| 摘要 |
The present invention relates to a sludge dehydration device which dehydrates moisture included in sludge generated in a process of treating organic matters of high concentration such as livestock excretions, food waste, a sewage treatment plant, and a digestion tank, dehydrates sludge having high moisture content, and minimizes sludge quantity which is finally emitted, and more specifically, to a screw press-type sludge dehydration device which has a shaft with a screw vane moving sludge, compresses sludge by differentiating the diameter of the shaft, reducing a space of the screw vain and a screen, and having a slant unit in the shaft, and maximizes a dehydration effect. |
